Product details
Overview
P6SMB82CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 70.1 V standoff voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB82CAHE3/52 datasheet, P6SMB82CAHE3/52 pinout, P6SMB82CAHE3/52 application, or P6SMB82CAHE3/52 equivalent, key selection considerations include bidirectional clamping symmetry, AEC-Q101 qualification for automotive use, SMB (DO-214AA) package compatibility, and thermal derating above 25 °C ambient.
Technical Context
This bidirectional TVS operates identically in both polarities, with symmetrical reverse standoff (70.1 V) and clamping (113 V) characteristics. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1 μA at VWM), while the low incremental surge resistance enables effective transient energy diversion without significant voltage overshoot.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. It meets J-STD-020 MSL Level 1 and is qualified to AEC-Q101, confirming suitability for automotive under-hood and infotainment applications requiring high reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ85CA | Higher VWM (72.2 V), higher VC (121 V at 5.0 A), same SMB package and 600 W rating. | Slightly looser clamping margin; better suited where higher standoff is needed without increasing VC disproportionately. | Select SMBJ85CA when design requires ≥72 V continuous reverse voltage tolerance with minimal layout change. |
| 1.5KE82CA | Through-hole DO-15 package, same 70 V VWM and ~113 V VC, but higher RθJA (~50 °C/W on larger pads). | Not suitable for high-density SMT designs; requires PCB real estate and manual or wave soldering. | Choose 1.5KE82CA only for legacy through-hole systems or prototyping where reflow compatibility is not required. |
Compared with SMBJ85CA and 1.5KE82CA, P6SMB82CAHE3/52 offers tighter clamping (113 V vs. 121 V), AEC-Q101 qualification, and optimized thermal performance in the low-profile SMB package - making it preferred for new automotive and industrial SMT designs demanding reliability and space efficiency.

FAQ
What is the standoff voltage (VWM) of the P6SMB82CAHE3/52?
The P6SMB82CAHE3/52 has a reverse standoff voltage (VWM) of 70.1 V, meaning it remains non-conductive up to this DC or RMS voltage level in either direction. This value ensures reliable operation under normal conditions while providing sufficient margin below its 77.9–86.1 V breakdown range. The P6SMB82CAHE3/52 maintains leakage current below 1 μA at VWM, supporting low-power system integrity.
Is the P6SMB82CAHE3/52 suitable for automotive applications?
Yes, the P6SMB82CAHE3/52 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment systems. Its construction includes glass-passivated junctions, MSL Level 1 moisture sensitivity, and operation up to 150 °C junction temperature - all validated per automotive reliability standards. The P6SMB82CAHE3/52 is explicitly designated for automotive use via the "HE3" suffix.
What does the "CA" suffix indicate in P6SMB82CAHE3/52?
The "CA" suffix in P6SMB82CAHE3/52 denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities - unlike unidirectional variants ending in "A". This eliminates polarity marking requirements and simplifies PCB layout for AC-coupled or floating circuits. The P6SMB82CAHE3/52 delivers identical VWM, VBR, and VC values in either direction, confirmed in the Vishay datasheet Section 1.
What is the maximum clamping voltage (VC) of the P6SMB82CAHE3/52 under surge conditions?
The P6SMB82CAHE3/52 has a maximum clamping voltage (VC) of 113 V at 5.3 A peak pulse current with a 10/1000 μs waveform. This represents the highest voltage imposed on the protected circuit during a standardized surge event. The P6SMB82CAHE3/52 achieves this with low incremental surge resistance, ensuring minimal overshoot beyond VC and preserving downstream component safety margins.
How does the SMB (DO-214AA) package of the P6SMB82CAHE3/52 compare to larger TVS packages?
The SMB (DO-214AA) package of the P6SMB82CAHE3/52 measures 4.06 mm × 3.30 mm × 2.20 mm, offering 40% smaller footprint than SMA (DO-214AC) and 65% smaller than DO-15 - while maintaining full 600 W peak pulse power. Its low 0.76 mm profile supports ultra-thin assemblies, and matte tin plating ensures compatibility with lead-free reflow profiles. The P6SMB82CAHE3/52's thermal resistance (100 °C/W) is optimized for standard 0.2" × 0.2" copper pads.
